expand-1/(2(5+4s-s^2))

expand

- \frac{1}{2 ( 5 + 4 s - s ^{2} )}

- \frac{1}{10 + 8 s - 2 s ^{2}}

Solution steps

- \frac{1}{2 ( 5 + 4 s - s ^{2} )}

Expand

2 (5 + 4 s - s^{2}) : 10 + 8 s - 2 s^{2}

= - \frac{1}{- 2 s ^{2} + 8 s + 10}

\frac{( x ^{2} + 7 ) ^{2}}{x ^{5}}

(- 4 x B)^{4}

(- 2 + 3 d = 6,) (2 n - 2 d = 4)

(3 = 6 - \frac{15 + 18}{9}) \cdot 9

\frac{10 x + 25}{( x - 1 ) ( x - 2 )}
